About five minutes in to the episode, they return to the Salazar ranch and the caption says "Las Nieves, New Mexico". It has been stated numerous times the Salazar ranch is in Las Nieves, Northern Mexico. This was fixed in the DVD release.
Near the end of episode 7 (7:00 p.m.-8:00 p.m.), Agent Chase Edmunds had managed to determine the location of the Salazars as being in Las Nieves, Mexico. A map of Mexico was pulled up on a computer screen that clearly shows Las Nieves, Mexico and yet near the beginning of episode 8 (8:00 p.m.-9:00 p.m.) when we are shown an exterior shot of Salazar's compound in Las Nieves, Mexico, the captioning at the bottom of the screen identifies the location of the compound as being in "Las Nieves, NEW Mexico" (the US state) instead of in the country of Mexico where it is actually located.
